Does Pro Red Code 16 stretch enough . . .

I got a pack of Pro Red Code 16 and I want to use it for 2 sets of mains. The racquets are Dunlop AG200 and MW 200G, which are very similar and have 18 x 20 string patterns, 95 sq" headsize. Klipper's chart for Dunlops says the AG200 uses 20 feet for the mains, but do I need to use more to make sure I'll have enough slack for tying off? Or will the Pro Red Code stretch enough?

I just strung my AG200 and used 21 ft. of Pro Red Code, for the mains. I wound up with 12" to tie off with on one side and 13" on the other. The stuff doesn't stretch much at all. Luckily I have a 90 sq" 16x19 racquet to use the other half on in the future.
